In the past, league officials have said the topic is impermissible and that persons asking such questions would be subject to discipline.

"The NFL and its clubs are committed to providing equal employment opportunities to all employees in a manner that is consistent with our commitment to diversity and inclusion, state and federal laws and the CBA. We are looking into the matter."
